British Railway Signalling Development in Colour

Book excerpt: In this colourful new book accomplished author Robert Hendry takes a company-based approach to the vast and complex subject of railway signalling. Although all companies were faced by the same essential need to ensure the safe passage of trains and the same basic regulatory framework, they each adopted different equipment and methods of operating. This helpful volume allows those interested in a particular company or region to follow the development of signalling by the company, and also to compare it with the often significant differences in the signalling solutions developed by others.
